Isingeniso
I-Ethyl ethynyl carbinol(Ethyl ethynyl carbinol) iyinhlanganisela yemvelo enefomula yamakhemikhali ethi C6H10O. Itholakala ngokungeza iqembu le-hydroxyl (iqembu le-OH) kupentyne. Izici zayo ezingokomzimba zimi kanje:
I-Ethyl ethynyl carbinol iwuketshezi olungenambala olunephunga elimnandi. Iyancibilika emanzini nasezincibilikisini eziningi eziphilayo ezifana notshwala, ama-ether nama-ester. Inomthamo ophansi, ilula kunamanzi, futhi inephuzu lokubilisa eliphakeme.
I-Ethyl ethynyl carbinol inokusetshenziswa okuthile ku-organic synthesis. Ingasetshenziswa njengento yokuqala futhi ephakathi ku-organic synthesis, futhi ivame ukusetshenziswa ekulungiseleleni izinhlanganisela eziqukethe i-carbonyl. Ingabamba iqhaza ku-alkyd esterification, ukwengeza kwe-olefin, ukusabela okugcwele kwe-hydrocarbon carbonylation. Ngaphezu kwalokho, i-1-pentin-3-ol ingasetshenziswa futhi ekuhlanganiseni odayi nezidakamizwa.
Indlela yokulungiselela i-Ethyl ethynyl carbinol ingenziwa ngezinyathelo ezilandelayo: okokuqala, i-pentyne ne-sodium hydroxide (NaOH) isabela ku-ethanol ukukhiqiza usawoti we-sodium we-1-pentyn-3-ol; ke, 1-pentyn-3-ol usawoti sodium iguqulwa Ethyl ethynyl carbinol usawoti by ukusabela acidification.
Lapho usebenzisa futhi uphatha i-Ethyl ethynyl carbinol, udinga ukunaka ulwazi olulandelayo lokuphepha: Iyacasula futhi ingase ibangele ukucasuka nokulimala esikhumbeni nasemehlweni, ngakho kufanele ugqoke izinto zokuzivikela ezifanele, njengamagilavu nezibuko. Ngaphezu kwalokho, iyavutha futhi kufanele igwenywe ukuthintana namalangabi avulekile noma imithombo yokushisa ephezulu, futhi igcinwe kahle. Noma yikuphi okunye ukuphatha noma ukugcinwa okuhlobene ne-compound kufanele kwenziwe ngokuhambisana nezinqubo zokusebenza eziphephile.
